Amtrak I need your thoughts on the possibility of water trains. My idea is that the rails could float on the water as to not disturb the fish while accounting for changing tides. I'm not sure how the trains would move but so far my only solution is one big pulley system

(water trains are NOT basically boats by the way. very important that i make this distinction)

Floating bridges do exist, for example between Seattle and Bellevue. But they are complicated and expensive and wouldn’t be practical for long distances like NYC-London or Vancouver-Tokyo
